Let the dimensions of rectangle be #a# and #b#

Area = #a*b#
Perimeter = #2*(a+b)#

Given: #a*b = 2*(a+b) => ab -2a -2b = 0#

Let's plot this
graph{(x * y - 2 x - 2 y )= 0 [-10, 10, -5, 5]}

As visible from the graph, there are infinitely many solutions to this equation. We know that #a,b# can only be positive, and still there are infinitely many solutions.

One such solution is #a =3, b = 6#, another one is #a=4,b=4#
